Method 3: Fan cycling is driven by an external signal (not supplied by RefPlus). Lower point of the cooling band set by user. Method 4: Fan cycling over a moving cooling band (variant of method 1). Lower point of the cooling band based on outside temperature and on a differential set by the user.
Page 8
METHODS 1 & 4 There are 3 typical scenarios when operating with method 1 or 4. These are the standard methods with fan cycling over a Cooling band; fixed for method 1 or moving for method 4. SCENARIO 1: • Fluid cooler has 20 regular ON/OFF fans (10 stages of 2 fans). Fans can be single or twin speed. •...

The modulating fan speed will also have this behaviour from the point where the last stage of regular fans starts to the point where the high-speed of regular fans starts (from 85˚F to 86˚F in our example). Beyond this point, the modulating fan speed increases proportionally over the next 1˚C (1.8˚F).

METHOD 3 Fan cycling is driven by an external signal (not supplied by RefPlus). This method allows the user to take control of the fans through two different ways: a communication card or an analog signal (DC voltage or milliamps). This external signal gives full flexibility and is completely configurable to be adapted to the user’s possibilities.

20. Using , set the Dynamic fan speed adjustment. This parameter allows the user to increase the modulating fan speed by changing the slope. Ex: If this parameter is adjusted above 0%, the maximum fan speed will be reached earlier. The following graphs show the difference between the modulating fan speed adjusted to zero and adjusted above zero.
